To all whom t may concern:

Be it known that I, BERTRAM J. GRIGSBY, a citizen of the United States, and a resident of Chicago, in the county -of Cook and have invented certain new and useful Improvements in Extension- Lamp Mountings for Vehicles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked' thereon, which form a part of this specification.

This invention relates to a novel extension lamp for vehicles, especially adaptable for automobiles, of .that character in which the lamp itself is detachablyI mounted on the vehicles and in which there is provided` alength of lconductor cord that normally is and is of such length as to permit the lamp,

` when detached, to be moved to any part ofthe vehicle or to be ,otherwise used about the vehicle within the length of the cord.

Among the objects of the invention is to 0 supporting means and a suitable length of conductor cord, normally wound on a reel to permit the moving of the lamp when detached to any required length from the point of attachment of the cord to the source of 5 energy. In order to provide for the proper protection of the length .of conductor cord when not in use, a housing or container, or a take-up device, such as 'a mechanical orr hand-operated reel, is provided.' This may D be permanently attached to any convenient part of the vehicle inside or outside of same, and supported separately from the lamp.

The lamp may be attachedtoany; usual part of the vehicle. If on" a motorcar, it tail lainp, windshield lamp, or the like.` For. thevpurposes of describing my invention, I will use the windshield lamp as an example.

In the drawings Figure 1 is a partial perspectiveview of an automobile, showing the" manner of applving my lamp thereto.

ig. 2 is a detail section of a portion of the dash, showingy one form of take-up reel i and container therefor. i

contained on a reel or like take-up device Fig. 3 is an enlarged rear elevation of the lamp with parts shown in section.

Fig. 4 is a section on the line 4-4 of Fig. 3, showing the manner of 'attaching the lamp casing to the bracket.

Fig. 5l illustrates another form of takeup reel. v.

As shown in the drawings, lOldesignates the lamp casing, 11 designates as a whole a supporting bracket therefor and 12 designates one of the windshield frame posts. rIhe bracket 11, when the lamp is employed isso constructed as to permit the lamp asa windshield frame supported spot lamp,

CaS-

ing lto be turned through large angles both' in horizontal and vertical directions so as t0 give the lamp an almost universal movement.

The particular form of bracket herein shown embraces a T-shape member, the cross arm 14 of which is shown as made hollow` and havingrat one end an extension 15 that isconnected to the lamp casing in a manner to be hereinafter described. The .central member or stud 16 is screw-threaded and extends upwardly through an opening ina bracket member`17 so as to rotate therein. Said bracket member is provided with Lclamping fingers 18 of any suitable type which are clamped on the .windshield frame post 12 throughthe medium of clamping bolts` 20. The shank or stud 16 of the T- shape bracket member is normally locked in place by means of a thumb nut 21.

The longer portion l15 ofthe cross arm of said T-shape itting 14 is tapered at 22 to enter a bushing 23 that is seated in an opening inthe adjacent. side of the lamp casing and maybe attached thereto in any suitable A manner, as by means of a flange 25 within the casing that is suitably shaped to fit the curvature of the casing. vThefiange may be Asoldered-01' riveted to the casing. The inner end of thetapered portion of the member 15 is threaded to receive a nut 26. By reason ofthe tapered portion 22 of the bracket arm and of the bushing 23 thenut 26 serves to force said tapers together andl to hold the casing reliably in place to maintain a given adjustment of the casing with respect to the bracket, while permitting thel casing to be adjusted in vertical directions about the longitudinal axis of the arm 15.

'A stop 29, extended fromaJ washer` 30, that is non-rotatively fixed to the threaded por.

mounted on the dash, in front thereof and.

within the cowl. Said reel is designated as a whole by 36 and is rotatively supported within a container or receptacle 38 that is fastened, as by means of screws 39, to the respect of the present invention,

The particular important in and the details-thereof will not be described, except to forward face of the dash. typevof reel employed is not state that the reel shown in Fig. 2 is an automatic winding reel and the shaft thereof is mounted inthe end Walls of the casing or receptacle 38. Current from a suitable source of supply, designated by 40, is carried to the conductors of the cord 35 through fixed terminal fingers 41 and conductor disks 42 that are fixed to the end faces of and rotate with the reel. rlhe dash is provided with an opening 43 through which the conductor cord extends, and the edge of said opening is preferably bound by a suitable non-friction washer or eyelet 44 to minimize -friction on the cord.

In Fig. 5 is shown a hand operated reel 45 that is mounted on any convenient fixed portion 46 of the vehicle. Said reel 45 rotates en a fixed shaft 48 and is provided with a handle 4S) to rotate it. Current may be carried to the conductors of the cord through fixed resilient terminal ingers 50 and 51 that contact with annular conductor members 52, 53, respectively, of unequal diameters that are fixed in any suitable manner to and ro- ,tate with the reel. The terminal fingers are connected to binding posts 5.5, 56 that are in turn connected to the source of electric energy.

In the normal use of the lamp it occupies its fixed station or position on the vehicle. depending upon the character or function of the lamp. In the illustrated embodiment of the invention, when it is desired to use the lamp as a trouble lamp, or to otherwise extend it from the car for other use, the thumb screw 21 is unscrewed from the stud 16 so 55 i as to permit the T-fitting 14 to be detached from the bracket member 17. The lamp is then free to be moved from place to lace within the range of the conductor cor 35, and the reel permits the cord to be extended or drawn away therefrom.

An advantage of the construction described is that the extension feature may be applied to standard lam s with little or no chan ein such lamps to a apt it to theextension unction. Further, the construction issuch that the appearance ofthe lamp is not changed.

It will be understood that the structural features are capable of some variation within the spirit and scope ofthe invention and that the invention is not limited to the exact details shown except as to claims whereinv said details are specifically set forth, or as imposed by the prior art.

claim as my invention:

1. As a new article of manufacture` a combined spot and trouble lamp, comprising a lamp casi a universal lamp-supporting bracket an vice; the bracket comprising a hollow arm adjustably connected to the lamp casing and a ri id arm having a swivel connection with the ollow arm at one end thereof and at the other end provided with means to attach the lamp to a wind shield frame; a lamp cord normally coiled within the. take-up device and extending through the hollow arm into the lamp casing; said take-up device having attaching means at one side thereof, to independently attach it to a part of the vehicle, and terminals to electrically connect the inner ends of the lamp cord.

2. An article of manufacture as set forth in claim 1, in which said hollow arm is provided with a portion substantially perpendicular thereto, and the rigid arm is provided `with an aperture to receive said perpendicular portion.

In witness whereof I claim the foregoing as my invention, I hereunto append my signature in the presence of two witnesses at Chi'pago, Illinois, this 22nd day of October, 191
